UPS power supply can be divided into two categories based on its working mode: backup and online. According to its output waveform, it can also be divided into two types: square wave output and sine wave output. When the backup UPS power supply is in normal power supply, the mains supply directly provides power to
Wide voltage adaptation rangeCapable of adapting to voltage standards in different countries and regions, with input voltage ranges of three-phase 190V-495V and single-phase 60V-280V (customizable), it can meet the usage needs in various voltage environmentsThe output voltage is stable and the voltage stabilization accuracy is high. If the output voltage is 220V ± 3%, it
The invention of DC/DC switching regulators has improved efficiency, but requires more complex design methods. Compared with the design of linear regulators, switching regulators utilize the energy storage characteristics of inductive and capacitive components to transmit power in the form of discrete energy packets. These energy packets are stored in the magnetic field of inductors
